While Baz Luhrmann and Leonardo DiCaprio premiere The Great Gatsbyin Cannesthis week, Warner Bros. has unveiled a gorgeous interactive journal chronicling the intensive research, scouting, and development stages behind the year’s splashiest adaptation. Below, a selection of photos, shared exclusively with VanityFair.com, that show the director’s field trips to see F. Scott Fitzgerald’s original manuscript, Long Island’s most Gatsby-esque mansions, and New York City’s elevated subway lines, which Luhrmann studied in order “to capture the light that Fitzgerald describes so eloquently.”
